Instead of having: #define __assign_str(dst, src) \ memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ? \ __data_offsets.dst##_ptr_ : "(null)", \ __get_dynamic_array_len(dst)) Use the ? : shortcut and compact it down to: #define __assign_str(dst, src) \ memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ? : "(null)", \ __get_dynamic_array_len(dst)) Link: https://lore.kernel.org/linux-trace-kernel/20240222211442.949327725@goodmis.org Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Chuck Lever <chuck.lever@oracle.com> Suggested-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the ReStructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
